To use the timecard scanner you'll need a simple scanner connected to your computer (set to code 128, same setup you'd use for all the other scanning station functions). Then each employee can print their own timecard on their log -in page right next to the 'clock in' button.
Then, you can set up any computer in your shop to be a timecard scanning station by simply clicking on the avatar in the top right hand corner and choosing "timecard scanner." Each employee can scan their times card quickly, rather that logging in to clock in and out.
It is safe for any employee or boss to open the timecard scanner and leave the station open for others to use because as soon as anyone navigates away from the timecard page the system will log you out.
